Here T ( 4, {} ) is reaching base condition in recursion, which returns 0 (zero ) distance. = { (1,2) + T (2, {3,4} ) 4+ 6 =10 in this path we have to add +1 because this path ends with 3. From there we have to reach 1 so 3->1 distance 1 will be added total distance is 10+1=11. john hancock hps

Splet25. sep. 2024 · For each intermedia node, it has a type. There are directed edges defined in the nodes (not between every node pairs) with different distances. My problem is: how to find out a shortest path which `` passes each type of node for at least once''? Is it a well-known problem, or any kind of variants of travelling salesman problem?

In March 2005, the travelling salesman problem of visiting all 33,810 points in a circuit board was solved using Concorde TSP Solver: a tour of length 66,048,945 units was found and it was proven that no shorter tour exists. The computation took approximately 15.7 CPU-years (Cook et al. 2006).
